When the second gasket 60 is configured in this way, noise generated when the unit slats 2 collide with each other during the opening/closing operation of the shutter can be remarkably reduced.

The first gasket 50 and the second gasket 60 may utilize the same member differently only in the location where they are to be installed.

Hereinafter, various embodiments of the body will be described with reference to the accompanying drawings. Parts that are the same as or similar to the preferred embodiment of the body described above will be omitted in detail in order to avoid duplication.

The specific action of the guide piece 19 will be described in more detail in another embodiment of the body to be described later.

Hereinafter, another embodiment of the body will be described with reference to the accompanying drawings. As shown in FIGS. 10 to 13, the body 70 in this embodiment has an upper engaging ring 11 and a lower engaging ring 12 formed at the upper end and lower end, respectively, and the inner space 14 is a guide plate ( 13) divided into two parts by the body part 10, the cover part 20 disposed to be spaced apart from the front surface of the body part 10 by a predetermined distance, and the upper part of the body part 10 and the cover part 20 and It can be defined as including a pair of insulators 30 that are respectively mounted between the lower portions to form a filling space between the body portion 10 and the cover portion 20 and a filler 40 filled in the filling space. .

The body part 10 is a member facing the indoor side based on the state in which the unit slat 2 closes the entrance, and may be formed in a profile shape in which top, bottom, front, and rear are blocked.

An upper engaging ring 11 may be formed on the upper surface of the body 10 , and a lower engaging ring 12 may be formed on a lower surface of the body 10 . The upper engaging ring 11 and the lower engaging ring 12 may be formed in a hook shape, and the upper engaging ring 11 has a lower engaging ring 12 of the adjacent unit slat 2, the lower engaging ring 12 Each of the upper engaging rings 11 of the adjacent unit slats 2 may be hooked to each other so as to be entangled.

The unit slats 2 adjacent to each other based on the upper engaging ring 11 and the lower engaging ring 12 may be rotated with each other.

The rear surface of the body part 10 is formed to be curved in an arc shape and is configured to have a complementary relationship with the shape of the cover part 20 to be described later.

This induces the cover portion 20 of the unit slat 2 adjacent to the body portion 10 of the unit slat 2 to come into closer contact when the unit slat 2 is wound on the winding roll 1, This is to minimize the volume of the insulated shutter in the rolled state.

At the upper and lower ends of the front surface of the body portion 10, the first fitting groove 17 to which the rear end of the heat insulating material 30 is fitted is recessed, the upper first fastener 15 and the lower first fastener 16 are provided. A protrusion may be formed.

The cover part 20 is a member facing the outdoor side based on the state in which the unit slat 2 closes the entrance, and is formed to extend long in the left and right directions to correspond to the length of the body 10, and It may be curved toward a convex arc shape. In addition, the guide line 21 may be recessed in the left and right longitudinal directions of the cover part 20 on the front surface of the cover part 20 . Through this, it is possible to disperse the outside wind pressure hitting the front of the cover part 20, so that effects such as noise reduction can be expected.

An upper second fastener 22 and a lower second fastener 23 protrude to face the upper first fastener 15 and the lower first fastener 16, respectively, on the rear surface of the cover part 20 and a second fitting groove 24 to which the front end of the heat insulating material 30 is fitted may be recessed in the second fasteners 22 and 23 .

The heat insulating material 30 is interposed between the first fasteners 15 and 16 and the second fasteners 22 and 23 facing each other to mechanically connect the body part 10 and the cover part 20 . The heat insulating material 30 may be formed to extend in left and right directions along the longitudinal direction of the body portion 10 and the cover portion 20 .

The insulator 30 may be composed of an upper insulator 30a mounted on the upper portion of the body portion 10 and the cover portion 20 , and a lower insulator 30b mounted on the lower portion, and by the insulator 30 , The charging space between the body part 10 and the cover part 20 may be sealed.

The heat insulating material 30 has a purpose of preventing the conduction of cold air or hot air to the indoor side, and may preferably be made of cured polyamide.

Polyamide has excellent physical properties, such as abrasion resistance, chemical resistance, and thermal insulation properties, so that it can provide structural strength to the unit slat 2 and ensure the thermal insulation performance of the unit slat 2 itself.

A protrusion piece 31 fitted in the first fitting groove 17 and the second fitting groove 24 may be protruded from the front and rear sides of the heat insulating material 30 .

The lower surface of the upper insulating material 30a is exposed to the charging space, and the upper surface is configured to be exposed to the outside between the body part 10 and the cover part 20 .

This is to improve the cushioning effect and airtightness by allowing the upper insulator 30a to make elastic contact with the first gasket 50 to be described later.

The filler 40 is composed of polyurethane foam filled with the filling space, and performs a thermal insulation function, like the thermal insulation material 30 .

It is revealed that the above-described heat insulating material 30 and filler 40 can be modified with a variety of known materials other than polyamide and polyurethane foam.

On the other hand, the unit slat (2) is mounted on the rear surface of the first gasket (50) and the body portion (10) mounted on the lower portion of the lower insulating material (30b) of the pair of insulating materials (30) a plurality of unit slats (2) A second gasket 60 configured to abut against the front surface of the cover portion 20 of the adjacent unit slats 2 when wound by the winding roll 1 may be further included.

The first gasket 50 and the second gasket 60 are members extending left and right along the longitudinal direction of the unit slat 2 , and may be made of an elastic material such as rubber or silicone.

In a state in which the unit slat 2 closes the entrance, for example, in a state in which a plurality of unit slats 2 are connected and installed in the upper and lower directions, there is a risk of draft and rainwater flowing between the adjacent unit slats 2, at this time, The first gasket 50 performs an action of closing the point between the adjacent unit slats (2).

For the mounting of the first gasket 50 , a first fitting jaw 18 is formed to protrude below the lower first fastener 16 on the body portion 10 , and the first fitting jaw 18 is formed on the rear surface of the cover portion 20 . A second fitting jaw 25 may be formed to protrude to face the first fitting jaw 18 . When configured in this way, a slit space is provided between the lower first fastener 16 and the first fitting jaw 18, and between the lower second fastener 23 and the second fitting jaw 25, and in this slit space The first gasket 50 is configured to protrude downward in a fitted state, and is configured to be in elastic contact with the upper surface of the upper insulator 30a of the unit slat 2 adjacent to the bottom.

In the process of operating the shutter, a damping effect can be expected by the elastic contact between the first gasket 50 and the insulator 30 , so that noise reduction is not only reduced, but also the point between the adjacent unit slats 2 is more hermetically sealed, It can also prevent rainwater from flowing in.

The second gasket 60 may protrude to the rear of the body portion 10 while being inserted into the rear groove 61 formed on the rear surface of the body portion 10 . As shown in FIG. 15 , the second gasket 60 makes elastic contact with the cover portion 20 of the unit slat 2 adjacent to the rear when the unit slat 2 is wound on the winding roll 1 to make contact noise. plays a role in reducing

When the second gasket 60 is configured in this way, noise generated when the unit slats 2 collide with each other during the opening/closing operation of the shutter can be remarkably reduced.

The first gasket 50 and the second gasket 60 may utilize the same member differently only in the location where they are to be installed.

On the other hand, on the front surface of the body portion 10, a circular guide piece 19 in which a part of the circumference is cut in a direction facing the body portion 10 is formed, and the guide plate 13 is formed with the guide piece 19 and It has a configuration for dividing the inner space 14 in the upper and lower directions by connecting between the rear surfaces of the body portion 10 .

By the interaction of the guide plate 13 and the guide piece 19 , the inner space 14 of the body portion 10 may be partitioned in the upper and lower directions, respectively.

At this time, the inner space 14 is configured as a vacant room to significantly lower the thermal conductivity of the unit slat 2 itself, thereby providing improved thermal insulation performance.

More specifically, the filler 40 filled in the charging space may flow into the inside of the guide piece 19 , and the cured filler 40 flowing into the guide piece 19 may be inserted into the guide piece 19 . The mechanical bonding strength with the is improved so that the filler 40 can be firmly fixed inside the charging space.

The unit slat 2 may further include a finishing cover 3 and a guide roller 4 respectively mounted on the left and right ends of the unit slat 2 .

At this time, the guide piece 19 may be utilized as a fitting groove for fitting the finishing cover 3 or the guide roller 4 configured at the left and right ends of the unit slat 2 as shown in FIG. 16 . can

The closing cover 3 may be respectively mounted on the open left and right ends of the unit slat 2 in order to prevent external exposure of the filler 40, at this time, the closing protrusion 3' of the magic sword cover 3 It may have a configuration that is fitted into the interior of the guide piece (19).

The guide roller 4 is a member for rolling contact with a guide structure (not shown) for guiding the unit slat 2 in the process of winding or unwinding the unit slat 2, and is a member for the left and right ends of the unit slat 2 It serves to reduce the frictional resistance between the unit slat (2) and the guide structure by supporting each rotation. At this time, the guide roller 4 may be provided with a fixed shaft 4 ′, and the fixed shaft 4 ′ has a configuration that is fitted into the guide piece 19 .

In addition, it is possible to guide the hot or cold air conducted to the filler 40 to the guide plate 13 by a pair of front tips 19a formed by cutting a portion of the circumference of the guide piece 19 .

Since the guide piece 19 and the guide plate 13 are formed to be relatively thin, a structure in which the hot or cold air conducted into the unit slat 2 can be more intensively induced is provided.

For example, in the case of summer, when the hot air (shown by the dashed-dotted line) induced through the guide piece 19 as shown in FIG. 14 is conducted to the guide plate 13, the upper, The air filled in the inner space 14 formed below cools the guide plate 13 by air to lower the temperature of the guide plate 13 .

That is, even if the heat conducted to the guide plate 13 is radiated from the guide plate 13 , the air accommodated in the inner space 14 rapidly cools the heat induced to the guide plate 13 , and as a result, the outdoor heat is transferred to the indoor side. A structure to prevent overturning is provided.

In addition, since the filler 40 and the insulator 30 biased toward the outdoor side primarily block the heat, and then block the heat secondaryly by the air filled in the inner space 14, the unit slat The heat shielding performance of (2) can be improved.

A structure is provided to prevent the outdoor cold air from being conducted to the indoor side due to heat exchange while raising the temperature of the cooled guide plate 13 with the air filled in it. When such a cold air blocking structure is realized, it is possible to prevent the condensation of water vapor on the rear surface of the body portion 10 due to the temperature difference between the outdoor and indoor sides.

In addition, since the filler 40 and the insulator 30 biased toward the outdoor side block the cold air firstly, and then block the cold air secondarily by the air filled in the inner space 14, the unit slat The cold air blocking performance of (2) can be improved.

On the front surface of the body portion 10, the auxiliary guide piece 19' may be additionally formed at the upper and lower portions with the guide piece 19 in the center. The auxiliary guide piece 19 ′ is similar in structure and function to the aforementioned guide piece 19 , and through this, effects such as an increase in mechanical coupling force with the additional filler 40 and an increase in thermal insulation performance can be expected.

On the other hand, in the summer season, the members such as the cover part 20, the filler 40, the heat insulating material 30 located on the relatively outdoor side thermally expand due to the rise in the outdoor temperature, and there is a risk that the unit slat 2 is twisted. , At this time, since the guide piece 19 and the auxiliary guide piece 19 ′ are strongly coupled to the filler 40 , the shape stability of the unit slat 2 can be ensured.

Hereinafter, a schematic assembly process of the unit slat 2 will be described.

First, the body part 10 , the cover part 20 , the heat insulating materials 30a and 30b , the first gasket 50 , the second gasket 60 , and the finishing cover 3 are prepared.

By fitting the upper second fastener 22 and the lower second fastener 23 , respectively, the assembly of the body part 10 , the cover part 20 and the heat insulating material 30 is completed.

With this configuration, a filling space may be formed between the body part 10 , the cover part 20 and the heat insulating material 30 , and the filler 40 is injected into the filling space thus formed.

When the injection of the filler 40 is completed, the closing cover 3 is mounted on the left and right ends of the opened unit slat 2, and the first gasket 50 is first fitted with the lower first fastener 16. Between the jaws 18, between the lower second fastener 23 and the second fitting jaw 25 is fitted in the slit space.

Next, the assembly of the unit slat 2 is completed by inserting the second gasket 60 into the rear groove 61 formed on the rear surface of the body portion 10 .
